A reloaded receiving corps coupled with Kaepernick’s continued growth in San Francisco’s offensive system has made Harbaugh a firm believer that his talented young signal-caller can raise his level of play.

“He just has the look and feel that he’s going to break out, more so than he already has,” Harbaugh said. "I’m really excited about everything about his game right now.”

Kaepernick started all 16 regular season games last season for the first time of his career. Kaepernick threw for 3,197 yards with 21 touchdowns and eight interceptions. The athletic passer added 524 yards on the ground and four rushing scores.

Harbaugh is of the opinion that Kaepernick can improve his statistics with the additions at wide receiver.

“I feel like we have a lot of firepower in our corner,” the coach said. “I feel like we have a lot of ammunition in our camp. I was just thinking about it the other day, ‘It doesn’t get better than this.’”

Harbaugh said the topic of discussion came up between he and Kaepernick, too.

“‘Kap’ said it the other day. He feels like he has a stable of receivers and maybe that’s the first time we’ve said that since we’ve all been here together,” Harbaugh said. “I concur. It feels that way.”

Even with a beefed up arsenal that now includes Stevie Johnson and Brandon Lloyd, Kaepernick has been respectful when voicing his opinion this offseason.

Entering the 2014 season, Kaepernick said he’s learning his new receivers' body language and figuring out how to incorporate their talents.

“This is the time of the year where you can be vocal and you can work on things a lot more because you don’t have to play Sunday,” he said. “So if you want to experiment with things, if you want to try things out, now is the time to see if we can get something new that is going to work for our offense.”

Kaepernick is talking the talk and walking the walk.

Harbaugh put it best, as to be expected.

“Athletically, he looks bionic,” the coach said of his star passer. “We all remember the 'Six Million-Dollar Man.’ That’s what he looks like to me. He’s very gifted and he always has been.”

Kaepernick is entering the final year of his rookie contract and if the quarterback is able to reach an agreement on a new contract before the season starts, he could become much more than a ‘Six Million-Dollar Man.’

Harbaugh said he remains hopeful that Kaepernick is signed long-term.

“On record as saying I’d like to see that happen,” the coach said. “It’s a process.”

Kaepernick said he’s not dwelling on the ongoing negotiations.

“I’m letting my agents handle all of that," he said. "I’m out here trying to get better with my teammates… I’m playing football regardless.”
